Hi

I have this kernel oops with WinTV NOVA T USB2
As you can see in the log the device is properly initialized. The
error happens when trying to actually get and play some video.
I use mplayer and after it tries to tune I get the oops in /var/log/messages.

I'm using kernel 2.6.16.20 and latest mercurial of today.
I can tell that with the mercurial version of 19.06.2006 evening
everything works.
I've seen some changes in dvb_frontend.c and .h the 21.06.2006, but I
don't really understand them.

Is there an more debug info I should provide?

Cheers

Mario
